IMPROVEMENT IN ENGINE-GOVERNORS.

To all whom Muay concern.'

Be it known that I, WILLIAM J. HALLEFAs, of Brooklyn, in the county of Kings and State of New York, have invented a new and Improved Mode of Operating Governor-Valves; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable those skilled in the art to make and use the same, reference being had to the accompanying drawings, forming a part of this specioation, in which- Figure l is a top view of my improved governing apparatus, and Fig. 2 is a side elevation of the same. Fig. 8 is a horizontal section, taken in the plane of theline a b in Fig. 2.

Similar letters of reference in the different figures indicate corresponding parts.

This invention relates to new and useful improvements in the appliances or agencies for operating the governor-valve of engines generally, but is designed more especially for regulating the supply ot' air in air-engines, and is connected with a valve and pipe having communication with the air-supply pump in such manner that when the speed of the engine increases above a given velocity the regulating or governor valve is opened and sufficient air allowed to escape from the feed-puml) to confine the movements ofthe engine to the desired maximum velocity.

My invention consists in combining with a centrifugal governora double inclined plane, which moves vertically between a pair of antifriction rollers attached to the valve-stem in such a manner that a very simple and sensitive movement is obtained for operating the escape or governing valve, as hereinafter fully set forth.

Having described the nature ot' my invention, I will proceed to describe its construe' and the secondary arms or connecting-links a a are pivoted to a second cross-head, b, which slides vertically on the spindle and carries the 'collar E and arms e.

To the outer end of arm e is rigidly7 secured a vertical rod, F, the lower end of which passes through a guide, H, and terminates with a portion,f, .which is deiiected or bent out ofline with the outer part, F, and which, to all intents and purposes, is a double inclined plane.

The deflected portion f ot' the rod Ff passes down between two anti-friction rollers, t and j, which are pivoted in the valve-stem k. The valve-stein k moves in guides l l.

m is the escape-valve, and closes the end of an escape-pipe',o1 Fig. 3, which communicates with the air-pum p.

The spindle C is geared to or may be belted to the driving-shaft S.

Its operation is as follows When the motion of the exigirle is increased suiiiciently to elevate the crosshead and arm b. e, then the double inclined planefis raised vertically and the roller j is acted upon bythe said inclined plane, and the escape-valve m is opened and air allowed to escape from the feeding apparatus of the engine; ,but as soon as the governor begins to fall the rod F descends, and the opposite inclined surface off acts upon the roller z' to close the valve. By these means a governing movement is obtained which acts with prom ptness and efficiency.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

The governor A A, when in combination with the inclined planes f, anti-friction rollers ij, and a valve-stem, 7c, arranged and operating substantially in the manner and for the purpose set forth.
